The war also gave a huge fillip to India's economy, industrialisation and employment. By the end of the war, India had, incredibly, spent more on it than Britain. On independence, Britain owed India a considerable “sterling debt”.
The Japanese 15th Army, 85,000 strong for the invasion of India, was essentially destroyed, with 53,000 dead and missing. Injuries and illnesses took many of the rest. There were 16,500 British casualties.
The war had drained India of troops and at one point a mere 15,000 soldiers were physically present in the subcontinent. For revolutionaries, like the Ghadar, this weakness was ripe for exploiting and their violent activities flourished – particularly in Punjab and Bengal.
